/**
 * RestController注解:
 *   1.组合注解,等价于 Controller + ResponseBody 注解;
 *   2.该注解会在每个控制器方法上添加@ResponseBody注解;
 * Slf4j注解:
 *   1.Lombok提供的日志注解,添加在类上,会自动生成日志对象log;
 *   2.日志对象log,会自动生成,使用日志对象log,记录日志;
 *     log.trace("xxx");
 *     log.debug("xxx"); -------------使用最多,开发过程中需要打印调试日志;
 *     log.info("xxx");
 *     log.warn("xxx");
 *     log.error("xxx"); -------------经常使用,记录错误日志[在全局异常处理器中使用较多];
